Iranian nuclear talks resume

Talks resumed over Iran’s nuclear programme hours after negotiators abandoned a deadline to reach the outline of a deal.

However, as the discussions dragged on, three of the six foreign ministers involved left the talks and prospects for agreement remained uncertain.

US secretary of state John Kerry claimed enough progress had been made to warrant an extension after six days of intense bartering, and huddled with his British and German counterparts in the Swiss town of Lausanne to continue a marathon effort to hammer out details of a framework accord.
